Hi, I've realised my gas supply pipe is not earthed near the meter and I believe it should be.
Can someone advise what size earth csa I need to add? I'm thinking 10mm2. (I find the IEE On-Site Guide a little confusing!)
It will be fixed to the outside wall of the house along the gas supply pipe route from the gas meter back to the main earth connection at the electricity meter so unprotected and about 10-15m in length, if that is relevant. The house has PME earthing.
Thanks in advance.
